I assume p is the semi-major axis and e the eccentricity. The peri- helion and aphelion are then given by p(1-e) and p(1+e), i.e., about 2.90 and 3.95 AU respectively. For Jupiter, they are 4.95 and 5.45 AU. If 1977 was after the temporary capture, this means that the comet ended up in an orbit that comes no closer than 1 AU to Jupiter's -- which I take to be a rough indication of how far from Jupiter it could get under Jupiter's influence. > Also, perihelions of Gehrels3 were: > > April 1973 83 jupiter radii > August 1970 ~3 jupiter radii Where 1 Jupiter radius = 71,000 km = 44,000 mi = 0.0005 AU. So the 1970 figure seems unlikely to actually be anything but a perijove.

I. Blackshear Jr." Subject: DSPSE (was Why Clementine?) Newsgroups: sci.space The SDIO has "contracted" with the NRL (Naval Research Laboratory) to fly the Clementine Mission. BTW we call it DSPSE (Deep Space Project Science Experiment). The NRL is building the spacecraft, designing the detailed mission and doing the integration and operations (with help from, JPL & Goddard & prob. some folks I have left out...don't be mad). I am on the TAMP (Trajectory Analysis & Mission Planning) team and am responsable for the IV&V of the traj that Goddard/CSC are designing. As for why SDIO is doing it, some of the reasons are: 1) the safety constraints are too tight to try to run the LIDAR in LEO 2) in LEO we don't get any new radiation data on the sensors, we will get that data on our 9 passages through the Van Allen (sp?) Belts 3) since we are going out there...why not piggy-back some general science 4) the intercept problem is a lot easied over LONG distances and LONG times I am sure there are some things I have forgotten, and some I haven't been told but, those are the reasons we all talk about. -- Jim Blackshear jib@bonnie.jsc.nasa.gov ------------------------------ Date: Sun, 18 Apr 1993 17:11:48 GMT From: Marcus Lindroos INF Subject: Into Infinity?(WAS:Re: *Doppelganger* (was Re: Vulcan?)

I was beginning to think that I had made that up. I remember that movie (it was about 1.5 hours long). I don't think they ended up anywhere in the known universe. I remember they got a message halfway out to Proxima Centauri, that Earth transmitted a day after they launched, timed to catch up with them at the halfway point. I thought it was neat, I think I was all of 10 at the time. >Does anyone know if "Into Infinity" has been released on video?

Rather than fix the code and possibly introduce new bugs, they just tell the crew 'ok, if you see a warning no. 213 before liftoff, ignore it'. - Jonathan ------------------------------ Date: Sun, 18 Apr 1993 18:36:11 GMT From: Ed McCreary Subject: SOFTWARE RELEASE for use with Voyager CDROMs Newsgroups: sci.astro,sci.space,comp.graphics T h e I m a g e M a c h i n e Version 1.0 by Eddie McCreary Introduction The Image Machine is a Windows based image processing package for use with the CDROMs distributed by the NSSDC containing data from Voyager and other spacecraft. It it intended mainly for use with these disks and should not be considered a general imaging application. Future versions will correct this. Features include: * Read compressed images directly from disk. No preprocessing required! * Basic image processing functions such as low and high pass filtering, zoom, rotate, flip, and much, much more! * Complete customizable filter kernels. Write your own filters if you don't like those provided with program. * Reseau mark removal. Get rid of unsightly reseau marks with the click of a button. * It's Freeware! Give it to your best friend, give it to your mother-in-law, give it to your dog, I just don't care! Media The Image Machine has been tested with the following CDROMs: * Voyagers to the Outer Planets, Vol. 1 - 12 * Mission To Mars: Viking Orbiter Images of Mars, Vol. 1 - 8 * Mars Mosaicked Digital Image Model, Vol. 1 - 6 * Mission To Jupiter: Galileo Images of Venus, Earth, & Moon, Vol. 2 - 6 * Magellan MIDR CDROMs (tested with only select images) It should be compatible with most images stored in PDS and VICAR format, but unless the image belongs to one of the above sets, it hasn't been tested. Requirements * 80386SX processor or above (20+MHz preferred) * 4 MB RAM, the more the better. * Microsoft Window 3.1+ Availability The Image Machine can be found on ames.arc.nasa.gov under pub/SPACE/SOFTWARE as imach10.zip. I've also submitted it to comp.binaries.ms-windows so if you don't have ftp access, wait a few days and it should appear at your site. Disclaimer The Image Machine is a private project written by myself in my spare time. I am in no way associated with the National Space Science Data Center or NASA and this project should not be consider endorsed by them. Thanks to Peter Yee for placing it on the ames archives.

If I read you right, you're saying in essence that, with a larger economy, nations will have more discretionary funds to *waste* on a lunar facility. That was certainly partially the case with Apollo, but real Lunar colonies will probably require a continuing military, scientific, or commercial reason for being rather than just a "we have the money, why not?" approach. It's conceivable that Luna will have a military purpose, it's possible that Luna will have a commercial purpose, but it's most likely that Luna will only have a scientific purpose for the next several hundred years at least. Therefore, Lunar bases should be predicated on funding levels little different from those found for Antarctic bases. Can you put a 200 person base on the Moon for $30 million a year? Even if you use grad students?
